Description
Technical Field
The utility model relates to a jet atomizer and an airflow guiding system of the jet atomizer, and belongs to the technical field of medical appliances.
Background
The atomization treatment is a common method for treating acute and chronic respiratory diseases of adults and children at present, and is routinely applied to the treatment of various respiratory diseases such as acute episode of bronchial asthma, acute episode of chronic obstructive pulmonary disease, bronchiectasis and the like. Aerosol inhalation has the following advantages over systemic administration: 1. the local drug concentration of the airway is high, and the effect is strong; 2. the medicine directly acts on airway epithelium and smooth muscle cells, and has quick effect; 3. the dosage of the medicine absorbed into blood circulation is very small, and the side effect of the whole body is small; 4. compared with oral administration, the medicine is not metabolized by liver, and has no first pass effect; 5. the preparation and application of the medicine are convenient. Due to the popularization of household medical equipment such as an atomizer, an oxygenerator and the like, atomization treatment can be carried out in hospitals and also can be used in families. Thus, nebulization therapy is very widely used.
The current common atomization treatment methods include jet atomization, ultrasonic atomization and vibration sieve mesh atomization. The three modes of atomization form aerosols from the drug solution by different means. Jet nebulization is the most widely used form of nebulized inhalation therapy. When the jet atomization treatment is carried out, the medicine solution is placed in the atomization tank, and when the high-speed airflow passes through the central tubule of the atomization tank, the medicine solution is sucked into the pipeline under the action of the Venturi effect and is impacted into micro-droplets along with the high-speed airflow, so that aerosol is formed, and the aerosol enters the airway to play a therapeutic role when a patient inhales. Thus, high velocity airflow is a key impetus for generating pharmaceutical aerosols. Jet atomization currently uses high pressure air or oxygen as the driving force. High pressure air is generated by the atomizer. The main structure of the atomizer is an air compression pump, which sucks ambient air, and forms high-speed air flow with constant flow rate (generally about 6-7L/min) through the action of the pump, and the air flow is output through an outlet with the aperture similar to that of an oxygen inhalation pipe, and is connected with an atomizing tank through a conduit, so that the air flow is led into the atomizing tank to manufacture medicine aerosol (see figure 2).
The defects are that: 1) The output of the atomizer is air, the oxygen concentration is 21%, and respiratory tract diseases patients often have hypoxia, and additional oxygen needs to be supplemented. However, the aerosol inhalation process usually requires 15-20 minutes, if the oxygen concentration cannot be increased, risks exist for the anoxic patients; 2) The temperature of the air output by the atomizer is room temperature and is greatly influenced by the ambient temperature, and cold air can stimulate bronchi of a patient suffering from respiratory diseases to cause bronchospasm so as to cause adverse reactions.
Another common source of high velocity air flow is high pressure oxygen through a wall line that supplies oxygen centrally, primarily for use in hospitals. When the method is used, the flow of high-pressure oxygen on the wall can be regulated by the gauge head and the humidifying tank, so that the output flow can be connected with the atomizing tank when the output flow is about 5-6L/min, and atomization treatment is carried out. The defects are that: 1) Can only be used in a hospital environment; 2) The high-speed airflow is pure oxygen, the oxygen consumption is high, and for patients with type II respiratory failure, such as slow lung obstruction, asthma and the like, the risk of aggravating carbon dioxide retention exists; 3) The temperature of the air flow is also room temperature, and bronchospasm is easy to induce.
In summary, the existing jet atomization or air or high-pressure oxygen cannot be used for adjusting the concentration and temperature of oxygen, which eventually causes the problems.
